Summary: RelMdColumnUniqueness for HepRelVertex
Key: CALCITE-1747
URL: https://issues.apache.org/jira/browse/CALCITE-1747
Project: Calcite
Issue Type: Bug
Components: core
Reporter: MinJi Kim
Assignee: Julian Hyde
In generated code/JaninoRelMetadataProvider, areColumnsUnique() is supported
for HepRelVertex, by using HepRelVertex.getCurrentRel(). In the underlying
RelMetadata (RelMdColumnUniqueness.java), the same code is disabled.
This is causing some problems for me since I am trying to use
RelMdColumnUniquess without going through the JaninoRelMetadataProvider For
me, enabling the same code in RelMdColumnUniquess solved the problem for me.
Although I am uploading a small patch for this soon, I wanted to see if there
were any concerns for enabling RelMdColumnUniqueness for HepRelVertex.
